From Low to High Coordinate Group 14 Compounds: Exploratory Chemistry

作为一个社会，我们越来越意识到人类活动对环境的影响，迫切需要开发更清洁的技术和更有效地利用我们的资源。贝恩斯是世界著名的主族化学研究员，专注于重14族元素不饱和衍生物的合成和化学研究。她的研究计划的长期愿景是利用她对不饱和第14族化合物化学的广泛知识和理解来提供创新的解决方案，以应对这些重要的社会挑战。建议的研究可分为三个主题。主题1：她建议合成配体稳定的硅化合物和配体稳定的二元锗和锡硫属化合物，并研究这些简单的络合物向纳米材料的转化。主题2：将研究两种将氨精制为胺的方法，氨是化学中许多领域中使用的试剂。她将探索利用氨基取代的锗或锡(II)化合物作为催化剂将烯烃插入氨的NH键中。她还将研究较重的第14族元素的双键化合物与氨的反应，作为合成功能化胺的第二种方法。主题3：她将开发合成具有重要技术意义的锗和锡化合物的替代方法，以避免使用高腐蚀性和有毒的氯基试剂。其愿景是为锗和锡的加工和再循环制定与工业有关的、高效和环保的议定书，以确保这两个重要元素将为子孙后代所用。将利用锗和锡的六配位络合物作为关键中间体，并将探索几种这类络合物的合成和反应活性。 贝恩斯研究计划将为学生提供极好的培训机会，其结果将提供新的知识，可用于解决两个重要的化学挑战：如何衍生氨和如何清洁地生产具有重要技术意义的材料。 2016年，贝恩斯获得了德国亚历山大·冯·洪堡基金会颁发的洪堡研究奖和加拿大化学研究所颁发的蒙特利尔奖章。2015年，她是奥尔登堡大学的DAAD学者(大学学者和德国学术交流服务的科学家的研究停留)。在过去的6年中，她发表了33篇期刊论文，2份数据报告，并发表了36次特邀演讲，其中包括4次全会。她管理过30家总部，其中包括几位国家奖学金获得者。她的总部已经在全球范围内做了31次会议报告。她指导过的学生中，超过90%的人作为学者和专业化学家直接为加拿大经济做出了贡献。

As a society, we are increasingly aware of the environmental impact of human activity and the dire need to develop cleaner technologies and to use our resources more efficiently. Baines is a world-renowned researcher in main group chemistry with a research focus on the synthesis and chemistry of the unsaturated derivatives of heavy Group 14 elements. The long term vision for her research program is to use her extensive knowledge and understanding of the chemistry of unsaturated Group 14 compounds to provide innovative solutions which address these important societal challenges. The proposed research can be divided into three themes. Theme 1: She proposes to synthesize ligand-stabilized silicon dications and ligand-stabilized binary germanium and tin chalcogenides and to examine the conversion of these simple complexes to nanomaterials. Theme 2: Two methods for the elaboration of ammonia to amines, reagents used in many areas of chemistry, will be examined. She will explore the insertion of alkenes into the NH bond of ammonia utilizing amido-substituted germanium or tin(II) compounds as catalysts. She will also investigate the reaction of doubly-bonded compounds of the heavier Group 14 elements with ammonia as a second method for the synthesis of functionalized amines. Theme 3: She will develop alternative methods for the synthesis of technologically important germanium and tin compounds which avoid the use of highly corrosive and toxic chlorine-based reagents. The vision is to develop industrially-relevant protocols for the processing and recycling of germanium and tin which are efficient and environmentally-friendly to ensure that these two important elements will be available for future generations. Hexacoordinate complexes of germanium and tin will be utilized as key intermediates and the synthesis and reactivity of several complexes of this type will be explored. The Baines research program will provide excellent training opportunities for students and the results will contribute new knowledge which can be used to address two important chemical challenges: how to derivatize ammonia and how to cleanly produce technologically important materials. Baines was awarded the Humboldt Research Award from the Alexander von Humboldt Foundation in Germany and the Montreal Medal from the Chemical Institute of Canada, both in 2016. She was a DAAD Scholar (Research Stay for University Academics and Scientists from the German Academic Exchange Service) at the University of Oldenburg in 2015. In the last 6 years, she has published 33 journal articles, 2 data reports and given 36 invited presentations including 4 plenaries. She has supervised 30 HQP, including several national scholarship winners. Her HQP have given 31 conference presentations across the globe. Over 90% of the students she has supervised are contributing directly to the Canadian economy as academics and professional chemists.
